Description

Technical Field

[0001] This utility model relates to the field of ecological slope protection technology, and more specifically, to a slope protection structure. Background Technology

[0002] Slope greening is a new and effective ecological slope protection method that protects exposed slopes. Combined with traditional engineering slope protection, it can effectively restore the ecological vegetation on slopes. The construction methods for slope greening include: grid beam backfilling combined with the slope protection structure; bag-stacking greening method; and direct spraying of greening nutrients via netting. To prevent slope collapse and soil erosion in mining areas, vegetation is typically planted on the slope for ecological protection. However, during dry seasons, reduced rainfall leads to decreased water supply for the vegetation, significantly impacting its growth and ultimately causing it to wither and die, directly affecting the ecological restoration effect of the slope protection.

[0003] To address the aforementioned issues, existing technologies provide a slope protection structure with a water collection device that collects rainwater during each rainfall for subsequent sprinkler irrigation of the slope. However, the water collection inlets of these existing devices are typically open, allowing dust and impurities to easily enter the collection chamber and further contaminate the water, affecting the effectiveness of sprinkler irrigation. Furthermore, the dust and impurities accumulated within the collection chamber are difficult to remove and clean. Utility Model Content

The side of the cover plate away from the rotating rod cooperates with the bottom stop of the support plate. The water collection tank has a guide port corresponding to the side of the cover plate away from the rotating rod. The guide port is used to allow the fluid in the water collection cavity to flow to the side of the cover plate away from the rotating rod so as to drive the cover plate to rotate and open the top opening of the water collection cavity.

[0008] Furthermore, the water collection assembly also includes a water guide plate disposed below the flow inlet and a force-bearing plate disposed below the water guide plate and on the cover plate. The water guide plate is inclined, and the top of the force-bearing plate has a relatively inclined force-bearing surface.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0031] like Figures 1 to 5As shown, an embodiment of this utility model provides a slope protection structure, which includes a slope 20, a protective embankment 10 disposed on one side of the slope 20, a water collection device 30, and a filtration device 40. The top of the protective embankment 10 has a water collection cavity 101. The water collection device 30 includes a water collection component 31 disposed on the top of the water collection cavity 101 and a spray component 32 buried in the slope 20. The water collection cavity 101 communicates with the spray component 32. The water collection component 31 includes a cover plate disposed at the top opening of the water collection cavity 101. 311, the cover plate 311 is adapted to the top opening of the water collection chamber 101 and is rotatably arranged according to the load-bearing condition to block or open the top opening of the water collection chamber 101; the filter device 40 is pluggably inserted into the water collection chamber 101 from one side of the slope surface 201 of the slope body 20 to filter the fluid flowing into the water collection chamber 101; the spray assembly 32 has a plurality of spray nozzles exposed on the slope surface 201 of the slope body 20 to spray the fluid collected in the water collection chamber 101 onto the slope surface 201 of the slope body 20.

[0032] This embodiment achieves effective rainwater collection and uniform spraying through the combined use of the water collection component 31 and the spraying component 32, solving the problem of water shortage for vegetation in traditional slope protection structures during the dry season. The cover plate allows for control of the opening and closing of the top opening of the water collection chamber 101, preventing dust and impurities from entering and clogging the flow channel when the top opening is normally open. Furthermore, the pluggable filter device 40 filters the fluid entering the water collection chamber 101, ensuring water cleanliness and facilitating the centralized treatment of filtered impurities, preventing clogging of the spraying component 32. This improves the reliability of water collection and sprinkler irrigation, ensuring vegetation survival rates, enhancing slope stability, and reducing maintenance costs.

[0033] Specifically, the water collection assembly 31 also includes a rotating rod 312 and a torsion spring 313. The rotating rod 312 passes through one side of the cover plate 311 and is rotatably located on the side of the top opening of the water collection cavity 101 near the slope 20. The torsion spring 313 is sleeved on one end of the rotating rod 312 and its two ends are respectively connected to the inner wall of the top opening of the water collection cavity 101 and the cover plate 311. The torsion spring 313 is used to drive the cover plate 311 to rotate and reset. The arrangement of the rotating rod 312 and the torsion spring 313 allows the cover plate 311 to automatically adjust its opening and closing state according to the amount of rainwater without manual intervention. The elastic force of the torsion spring 313 provides the reset force for the cover plate 311, ensuring that the water collection cavity 101 can be closed in time after the rain stops, thus achieving isolation and protection of the water collection cavity 101 while preventing water evaporation. Specifically, when the amount of rain or water accumulation on the side of the cover plate 311 away from the rotating rod 312 is large, it will be pressed down, causing the cover plate 311 to rotate around the rotating rod 312 and open the top opening of the water collection chamber 101. The torsion spring 313 will accumulate torsional force, allowing rainwater to enter the water collection chamber 101 through this opening. As the amount of rain or water accumulation gradually decreases, the force on the side of the cover plate 311 away from the rotating rod 312 will be less than the torsional force of the torsion spring 313. Under the action of the torsional force, the cover plate 311 will reset and rotate, closing the water collection chamber 101. This configuration realizes automated or semi-automated water collection of the water collection assembly 31, which helps to reduce labor costs.

[0034] It is understood that in other embodiments, the torsion spring 313 may be replaced by a hydraulic or electric drive.

[0035] Furthermore, the water collection assembly 31 also includes a support plate 314 disposed on the top of the side of the protective dike 10 away from the slope 20 and a water collection tank 315 disposed above the support plate 314. The support plate 314 is partially located above the top opening of the water collection cavity 101 on the side away from the slope 20. The side of the cover plate 311 away from the rotating rod 312 cooperates with the bottom stop of the support plate 314. The water collection tank 315 has a guide port 3151 corresponding to the side of the cover plate 311 away from the rotating rod 312. The guide port 3151 is used to allow the fluid in the water collection cavity 101 to flow to the side of the cover plate 311 away from the rotating rod 312 so as to drive the cover plate 311 to rotate and open the top opening of the water collection cavity 101. By setting a water collection tank 315 with a diversion port 3151, rainwater can be collected and discharged from the diversion port 3151. This increases the impact and downward pressure on the side of the cover plate 311 away from the rotating rod 312, thereby driving the cover plate 311 to open and realize automatic rainwater collection.

[0036] The water collection assembly 31 also includes a water guide plate 316 disposed below the flow guide port 3151 and a force-bearing plate 317 disposed below the water guide plate 316 and on the cover plate 311. The water guide plate 316 is inclined, and the top of the force-bearing plate 317 has a relatively inclined force-bearing surface.

[0037] In this embodiment, the arrangement of the water guide plate 316 and the force plate 317 optimizes the rainwater flow path and improves the response speed of the cover plate 311. The water guide plate 316 directs the rainwater to the force plate 317, and the inclined design of the force plate 317 increases the impact force of the water flow on the cover plate 311, enabling the cover plate 311 to open quickly, making the water collection response faster and more effective in collecting rainwater, reducing rainwater loss, and providing sufficient water for vegetation.

[0038] It is understood that in other embodiments, the angles of the water guide plate 316 and the force plate 317 can be adjusted to adapt to slopes 20 with different slopes, so as to quickly improve the rainwater collection efficiency; a water collection area can also be set on the force plate 317 or at the position where the force plate 317 guides the water flow, so as to facilitate the rapid drive of the cover plate 311 to rotate (wherein, a small hole can be set at the bottom of the water collection area so that the water in the water collection area can be slowly discharged after the cover plate 311 is opened, so that the cover plate 311 can be reset).

[0039] like Figures 1 to 3 As shown, the interior of the water collection tank 315 has a strip-shaped water collection trough 3152, the bottom of which gradually increases in the direction from the guide port 3151 towards both ends. This design allows rainwater entering the strip-shaped water collection trough 3152 to converge towards a lower position and be discharged from the guide port 3151, which is beneficial for the concentrated discharge of rainwater and increases the discharge speed. This, in turn, further enhances the impact of the discharged rainwater flow on the load-bearing plate 317, ensuring that the cover plate 311 can be opened stably.

[0040] like Figure 2 and Figure 3 As shown, the sprinkler assembly 32 includes a pump body 321, a connecting pipe 322, and a sprinkler plate 323 with the same inclination angle as the slope surface 201 of the slope 20. The connecting pipe 322 is connected to the bottom of the water collection chamber 101 through the pump body 321. The sprinkler plate 323 is adapted to the slope surface 201 of the slope 20 and is buried below the slope surface 201. The slope surface 201 has multiple planting holes 202. Some of the planting holes 202 are used for planting vegetation, and the sprinkler plate 323 corresponding to the other planting holes 202 is provided with a sprinkler head 324 with a spray nozzle. In this embodiment, the spray fluid of the sprinkler head 324 can cover at least all areas planted with vegetation. The pump body 321 pumps rainwater from the water collection chamber 101 to the sprinkler plate 323 through the connecting pipe 322. The sprinkler head 324 disperses the rainwater and sprays it out so that it can cover the vegetation planted on the entire slope surface 201, promoting vegetation growth.

[0041] like Figures 1 to 5As shown, the top area of ​​the slope 20 has a hollowed-out area 203 for installing a filter device 40. The filter device 40 includes a positioning component 41 and a filter plate 42 with multiple filter holes 421. The top area of ​​the water collection cavity 101 has a through hole 102 on the side facing the slope 20, and a limiting groove 103 on the side away from the slope 20. One end of the filter plate 42 extends into the water collection cavity 101 through the through hole 102 and is limited and installed in the limiting groove 103. The other end of the filter plate 42 is located outside the water collection cavity 101. The positioning component 41 is located at the hollowed-out area 203 and has a positioning end that can be plugged into the filter plate 42. This configuration ensures that rainwater entering the water collection chamber 101 is filtered, preventing impurities from clogging the spray assembly 32 or accumulating inside the water collection chamber 101. The filter plate 42 is detachably installed inside the water collection chamber 101 via the positioning assembly 41, facilitating regular cleaning or replacement. This improves the efficiency and effectiveness of the water collection and spraying process and extends its service life. Furthermore, the design of the recessed area 203 reduces the exposure of the filter device 40 and facilitates the positioning of its installation location.

[0042] The filter plates 42 can be made of different materials or have different pore sizes to meet the needs of vegetation growth in different regions and improve the filtration effect. The filter plates 42 are equipped with handles 422 for easy assembly and disassembly.

[0043] Specifically, the positioning component 41 includes a fixing block 411 fixedly disposed at the hollowed-out area 203 and a lifting rod 412 passing through the fixing block 411. The fixing block 411 is located above the filter plate 42, and the bottom end of the lifting rod 412 forms a positioning end. In this embodiment, the combination of the lifting rod 412 and the fixing block 411 simplifies the installation and disassembly process of the filter plate 42. The bottom end of the lifting rod 412 is inserted into the filter plate 42 for positioning, and the lifting action of the lifting rod 412 can easily disassemble the filter plate 42. This design makes the maintenance of the filter plate 42 simple and quick, reducing maintenance costs.

[0044] Furthermore, the positioning component 41 also includes an elastic element 413. The fixing block 411 has a stepped structure 4111 for the hole section through which the lifting rod 412 passes. The lifting rod 412 includes a first rod body 4121 and a second rod body 4122. The radial dimension of the second rod body 4122 is larger than that of the first rod body 4121, and one end of the second rod body 4122 facing away from the first rod body 4121 forms a positioning end. The elastic element 413 is sleeved on the outer periphery of the first rod body 4121, and its two ends abut against the second rod body 4122 and the stepped structure 4111, respectively. With this configuration, the elastic element 413 provides an automatic positioning function for the filter plate 42, simplifying the installation steps. When the lifting rod 412 rises, the elastic element 413 is compressed, and the positioning end rises accordingly, spacing itself in the height direction from the required installation position of the filter plate 42. At this time, the filter plate 42 can be inserted or removed. Afterward, the lifting rod 412 is released, and it will automatically reset under the action of the elastic element 413. This design helps to shorten the disassembly and assembly time of filter plate 42 and improves the convenience of disassembly and assembly.

[0045] Preferably, there are multiple lifting rods 412, and the bottom end of any one of the lifting rods 412 forms a corresponding positioning end. The positioning assembly 41 also includes an adapter rod 414, and the multiple lifting rods 412 are connected in pairs through the adapter rod 414. The combination of multiple lifting rods 412 and adapter rod 414 improves the positioning accuracy and stability of the filter plate 42. The adapter rod 414 makes the movement of the lifting rods 412 more synchronized, avoiding positioning failure caused by uneven force at a single point.

[0046] In summary, this utility model provides a slope protection structure that, through the combined use of the water collection component 31 and the sprinkler component 32, achieves effective collection and uniform spraying of rainwater, solving the problem of water shortage for vegetation in traditional slope protection structures during the dry season. The cover plate allows for control of the opening and closing of the top opening of the water collection chamber 101, preventing dust and impurities from entering and clogging the flow channel when the top opening of the water collection chamber 101 is normally open. Furthermore, the pluggable filter device 40 filters the fluid entering the water collection chamber 101, ensuring water cleanliness and facilitating the centralized treatment of filtered impurities, preventing clogging of the sprinkler component 32. This improves the reliability of water collection and sprinkler irrigation, ensures vegetation survival rate, enhances slope stability, and reduces maintenance costs.

[0047] In one specific embodiment, during heavy rain, rainwater will flow through the strip-shaped water collection channel 3152, and then flow towards the cover plate 311 through the guide port 3151 on the outer wall of the strip-shaped water collection channel 3152 and the guide plate 316. When a large amount of rainwater impacts downward through the guide plate 316, the force plate 317 will be subjected to the impact force, which will then drive the cover plate 311 downward to rotate via the rotating rod 312. During the rotation, the rotating rod 312 will compress the torsion spring 313. The cover plate 311 opens the top opening of the water collection chamber 101. With the impact of a large amount of rainwater, the force plate 317 will be continuously squeezed, so that the cover plate 311 is always in the open state. The rainwater flows into the water collection chamber 101 through the opening and accumulates in the water collection chamber 101. As the amount of rainwater decreases, the impact force on the force plate 317 decreases, and the torsion spring 313 will release the torsional force to drive the cover plate 311 to reset and rotate, thereby re-closing the top opening of the water collection chamber 101. When rainwater flows into the collection chamber 101, it is filtered by the filter plate 42, which filters impurities in the rainwater and prevents them from clogging the pump body 321. When the filter plate 42 needs to be cleaned or replaced, the adapter rod 414 is pulled upwards. The adapter rod 414 will then move the lifting rod 412 upwards. During the movement of the lifting rod 412, the elastic element 413, which is pressed between the stepped structure 4111 and the second rod body 4122, will be compressed. 412 will then disengage from the filter plate 42, thereby releasing the positioning effect on the filter plate 42. Then, pull the handle 422 outward, thereby moving the filter plate 42 outward until the entire filter plate 42 is pulled out of the water collection chamber 101. Release the adapter rod 414 to complete the disassembly. During installation, similarly, first pull the adapter rod 414 upward, then insert the filter plate 42 and align the positioning end of the lifting rod 412 with the through hole on the filter plate 42. Then release the adapter rod 414, and the lifting rod 412 will move downward under the action of elastic force and penetrate into the filter plate 42, completing the positioning of the filter plate 42. Furthermore, when it is necessary to spray the slope 201 with rainwater collected in the water collection chamber 101, the pump body 321 can be activated to transfer the rainwater inside the water collection chamber 101 to the spray plate 323 through the connecting pipe 322. Then, the rainwater is sprayed onto the vegetation planted on the slope 20 through the planting holes 202 opened on the slope 20. In this way, the vegetation can be continuously irrigated during the dry season, preventing the vegetation from withering due to drought and greatly improving the ecological restoration effect of the slope 20.
